Changing Saw Blade
1. Unplug the electrical cord or open the circuit breaker in the branch circuit. The saw must be turned off and power disconnected any time saw blades are being changed.
2. Pull open both upper and lower drive wheel guards.
3. Release blade tension completely by turning the tension handle fully counterclockwise.
4. Remove table leveling pin. The pin has a tight push fit in its slot; it is not threaded.
5. Use a screwdriver to pop out the table insert.
6. Loosen the set screws that lock the guide blocks. Move the guide blocks outward. Then turn the micro-adjusting knob to move the blade support bearing to the very rear of its travel.
7. Use a hex wrench, loosen the set screw that locks the lower blade guide and support assembly. Move the assembly to the very rear of its travel by using the micro-adjusting knob on the back side of the assembly.
8. Use a hex wrench, loosen the carbide blade guide set screws. Open up a reasonably large gap between the guides; do this on both the upper and lower blade guides.
9. Carefully remove the blade from the drive wheels. Remove the blade out of the saw table through the table.
10. Clean out the interior of the saw with a shop vacuum. Examine the bearings and other exposed mechanisms of the saw.
11. Ease the replacement blade into the table slot and over the upper and lower drive wheels.
- NOTE: It is possible to install the blade upside down. Make sure the teeth on the blade are pointing downward.
- NOTE: The blade should be “free standing” at the cutting throat; the upper and lower blade guides should not touch the blade at any point.
- Note: Make sure the blade is in the slot in the blade guard on the left side of the machine frame.
12. Apply tension to the blade using the tension knob. The tension levels for various blade widths are shown on the markings on the tension device.
13. Slowly turn the upper drive wheel by hand,while OBSERVING THE BLADE TRACKING. The blade should track, more or less, in the center of the drive wheel. If the blade does not track true, adjust the tracking to keep the blade centered.
14. Unlock the tilt adjustment knob by loosening its locking wing nut. Both the adjustment knob and wing nut.
15. Turn the tilt adjustment knob (usually a VERY LITTLE at a time) to adjust the tilt of the upper drive wheel. Do this while turning the upper wheel by hand, and adjusting until the blade stays centered on the wheel.
16. Tighten the tilt mechanism locking wing nut.
17. Using the micro-adjusting knob, move the lower blade support assembly forward until the support bearing just contacts the back edge of the saw blade.
18. Adjust the lower carbide blade guides until they just contact the sides of the blade. Make sure the guides DO NOT CONTACT THE TOOTH PORTION OF THE BLADE. The guides should touch only the flat part of the blade. After correctly positioning the carbide guide blocks, tighten the set screws securely.
19. Adjust the upper support assembly so the support bearing just contacts the back edge of the saw blade.
20. Adjust the upper carbide blade guides until they just make contact with the blade BEHIND THE TOOTH AREA OF THE BLADE. Then tighten the set screws securely.
21. Replace the table insert.
22. Insert the table pin into its slot.
23. Close the drive wheel guards.
24. Plug the electrical cord into power source or close the circuit breaker on the branch circuit.
25. Turn on the power and observe the action of the blade to sure the blade is correctly adjusted.
Draining and refilling the reduction gearbox:
1. Unplug the electrical cord or open the circuit breaker in the branch circuit.
2. Open the door in the base.
3. Push up on the motor to loosen the drive belts.
4. Remove the pipe plug at the bottom of the gearbox. Drain the oil into a suitable container for safe and appropriate disposal.
5. Replace the drain plug.
6. Open the filler plug.
7. Add lubricant until the level is halfway up the sight gauge window. Use Shell Spirax HD 90 gear lubricant.
8. Replace the filler plug.
9. Replace the drive belts. Allow the motor to pivot downward to apply tension to the belts.
10. Close the access door.
11. Plug the electrical cord into the power source or close the circuit breaker on the branch circuit.
